Release Notes for Beta 2

Fixed router bugs. Now bridge.example.com and example.com/bridge are
both acceptable ways to access the bridge (this decision is left to user
configuration, of course).

Bump minimum Halite version to 2.1.

Implemented Keyggdrasil,
an Airship-exclusive protocol that allows us to guarantee that all Airships
have the same public key and package update history. This is accomplished
by a peer verification mechanism.

Improved Airship Installer workflow.

Added command line scripts to install new Cabins, Gadgets, and Motifs.

When you change a blog post's slug, you can optionally create an HTTP 301
redirect to the new URL to prevent visitors from getting an unfortunate
HTTP 404 error. This allows you to funnel traffic towards a meaningful
destination.

Implemented the redirect management section. Now you can edit/delete custom
URL redirects (some of which are created when you delete/rename content).

Greatly improved the comment system; now you may reply to other comments.
